Every mechanical attribute read in MJCF now derives from mjcf.schema.
generate_read_table.py emits typed mjXAttr rows (mjcf_read_table.inc,
doc_test-gated) binding each attribute to its spec struct field; field
offsets are offsetof() expressions, so binding mistakes are compile
errors, and the field's C type -- parsed from the headers -- selects the
row kind, so mjtNum-versus-double is decided by the struct, not the
schema. mjXReader::ReadAttrTable is the generic loop; its static core
also serves the section parsers and records XML-authored fields via
mjs_setAuthored for attach conflict resolution. Row kinds cover
strings, string lists, numeric scalars and vectors (exact and ranged),
enums (int- and byte-width), bitwise flag sets, bools, unbounded typed
vectors, fixed char arrays, and identity constants declared by 'set'.
The rows are inline variables, and carry the writing=custom flag,
because the writer will share them.
The keyword maps the rows reference are generated too: the ~48
hand-written mjMap tables become mjcf_map.h, one map and size constant
per enum as C++17 inline variables, retiring the hand-maintained
extern block in xml_base.h. Map names follow the schema enum names
(fluid->fluidshape, TFAuto->FalseTrueAuto, FAuto->FalseAuto,
joint->jointtype, geom->geomtype, jac->jacobian); all maps are
key-order- and value-identical to the hand tables they replace, and
bool_map is hand-emitted (the bool type is built in, not a schema
enum).
The OneX() parsers reduce to genuine irregulars, schema-marked as
reading=custom: orientation alternatives, file attributes (VFS and
asset-dir context), the actuator shorthand remappings and per-type
input maps, springlength's one-value copy, mesh builtin construction,
hfield elevation, texture cube files, flexcomp seeding, the memory
suffix parse, and the flag bit families. All 41 sensors that are pure
identity-plus-references -- including the frame family and insidesite
-- dispatch through a generated tag table; frame-sensor
objtype/reftype vocabulary tightens from the full mju_str2Type
namespace to the documented body/xbody/geom/site/camera subset, so an
invalid keyword now fails at parse time instead of compile time. The
equality family and both tendon types read shared group rows; the
twelve actuator shorthands share the general rows, with per-tag
legality enforced by the schema check. Sections bind non-mjs structs,
the visual sub-sections reaching their anonymous sub-structs through
member paths declared by an element-level field= facet.
Latent irregularities surfaced by the migration and preserved via
schema declarations or remnants: key's name is set even when absent,
eulerseq and gridlayout are fixed char arrays (chars[n], arity in
characters), gridlayout's length-must-match-gridsize stays a
value-conditional remnant, and constructor-style elements (tendon
wraps, asset model, replicate, attach) are annotated as such -- their
attributes are arguments, not field writes.
Two coherence tests guard the schema against the C sources: every
schema enum constant must be a member of the C enum it claims, and
every C member must be a keyword, a count sentinel, or a documented
exemption; and generate_default_table.py emits one row per defaulted
attribute (mjcf_default_table.inc), compared by SchemaDefaultsTest
against a freshly-constructed spec -- the schema cannot disagree with
the C default-constructors without failing the suite.
Verified: doc_test regenerates and diffs every artifact; the full
suite; and an A/B harness compiling the model corpus against the
pre-migration reader -- saved XML and binary models are byte-identical.

All instances of mujoco_test in the code base were followed by
a call to target_link_libraries(<testname> fixture gmock).
As anyhow mujoco_test already was calling target_link_libraries
to some predefined list of targets (mujoco and gtest_main),
this PR adds to the list of default linked targets also fixture
and gmock, to reduce the boilerplate.
Furthermore, to completly remove the need for calling
target_link_libraries after a call to mujoco_test, this PR also
add to the mujoco_test macro the ADDITIONAL_LINK_LIBRARIES
argument, that can be used if a given test needs to link some
additional targets beside the default ones.
To permit to use these new features also for mujoco benchmarks,
this PR adds a MAIN_TARGET parameter to mujoco_test, to select
if gtest_main or another target is used to provide the main
entry point to the test executable.
